I am calling the ZXing scanner from Screen-A using intents. Once the scan is done control of course returns to the code behind Screen-A and I do some other work before calling Screen-B. Problem is the screen is black during this work period and I cannot determine the proper context to use to display a "working..." Toast/msgbox.

I wish to have one application that runs in the background, which knows when any of the built-in applications (messaging, contacts, etc) is running. So my questions are: How I should run my application in the background. How my background application can know what the application currently running in the foreground is.

I have an XML preferences screen which is handled by addPreferencesFromResource. On it, there is a ListPreference, for which I want the summary to contain the current value of that preference. I think this would be a common requirement, as otherwise you could not see the present value of the preference without expending a click. I read that the summary field supports resource references, and I see that I can refer to preferences as android:summary="@+preference/prefname" in my ListPreference. Clearly this is why resource references would be supported in this field. However, when I try this, instead of the present value of prefname, the text "false" appears as the summary. Does anybody know how to display a current value without taking the seemingly ridiculous step of rewriting the entire (large) preference screen in Java?
View 5 Replies View RelatedSo this is related to a question I asked earlier. I am trying to display an alert using a specified layout. My layout is:
And the code to call and show the alert dialog is..
When I run it I get an error saying:
Uncaught handler: thread main exiting due to uncaught exception
android.view.WindowManager$NadTokenException: Unable to add window -- token null is not for an application
I've looked through the android development site and can't figure it out. I think I'm just missing something obvious but the fix isn't jumping out at me. How can I get this alert dialog to display?
I want to display an alert asking "do you want to exit from the application yes/no?" before exiting the application (when we click the Back button).
View 5 Replies View RelatedThis must come up very often. When the user is editing preferences in an Android app, I'd like them to be able to see the currently set value of the preference in the Preference summary.
Example: if I have a Preference setting for "Discard old messages" that specifies the number of days after which messages need to be cleaned up. In the PreferenceActivity I'd like the user to see:
"Discard old messages" <- title
"Clean up messages after x days" <- summary where x is the current Preference value
Extra credit: make this reusable, so I can easily apply it to all my preferences regardless of their type (so that it work with EditTextPreference, ListPreference etc. with minimal amount of coding).
I am new to android and not being able to display current location on map so can you provide me the code for displaying Location with manifest.xml and main.xml.

View 4 Replies View RelatedI've had my Hero on Orange for 4 or 5 days now and apart from when I first switched on the phone the weather app has just said "No weather data available" and the clock/weather widget has just had my location. I have the "location by cell" thing switched on, and I did manage to get it working once with the GPS, but other than that it just displays my location. It's the same whatever location I am in. The other cities download the weather just fine (London, Paris, New York, etc.). It's not like I'm somewhere tiny either, I am in Bromley. It doesn't make any difference whether I'm using WiFi or 3G.

View 2 Replies View RelatedAny widget that will display a moving google map with my current location centered? There are a couple apps I've found that are close, they just don't update in realtime. The reason I ask is because I have my 7" galaxy tab mounted in my truck. I use a program called torque to add gauge widgets (coolant temp,boost pressure, rpm,etc) to my home screen and would like to have a moving map display as well. I understand this would be a battery hog,but the tablet is always plugged in.

View 3 Replies View RelatedIn my actual project I need to draw a MapView with a given running/walking/cycling path on top of it. I don't need the current position so I added an overlay just for the path (no MyLocationOverlay). The path is painted but I don't see the Map in the emulator - only the grey tiles. The apiKey is set in the layout (MapView) and INTERNET permission is set in the Manifest. So I'm wondering if I need more. Is it the emulator simply not working well (I do have 3G and 2 bars in the emulator) or do I need something else? Do I need to build an additional overlay or add additional permissions (xxxLOCATION) to the Manifest.

View 1 Replies View RelatedMy question is- with the telephony manager, is there a way to determine what number the phone is off hook with? I thought getLine1Number() might return that phone number that is being dialed, but it is not what I expect. I am working with 2 emulators, and added a log line so that I could see what that method is doing. When dialing another emulator, I expected getLine1Number() to return 5554, but it was 15555218135. Perhaps there is another method I should be using instead? Do I need to be into the source code to get the information I want?
View 1 Replies View RelatedI was wondering if there is a way to determine who passed an intent to my application. For example, I have a service, that I want to act differently depending on who passed the intent (for security reasons). I'm trying to sandbox each calling application, so they only have access to their data stored in my application.
For it to be secure, I cannot trust any application to be truthful about the identifying data it is passing into my service. Therefore, I need some system way of identifying who sent the intent in a way that the calling application cannot change that information. I don't know if it is possible, but I can't find anything in the Intent class, and I was wondering if there may be another structure which does what I want it to. If it is not possible, I would like to get some type of mechanism to do this in the roadmap.
I'm using a UNIX socket to facilitate communication on and Android device between a system level daemon I've got running in C and an application I've got running in Java. I'm much more of a C coder than a Java coder, so I'm having some issues when trying to read in data from the socket on the Java side. Currently, my code is as follows:
try{//Prepare to write the command and read the ACK
InputStream is = receiver.getInputStream();
OutputStream os = receiver.getOutputStream();
BufferedReader in = new BufferedReader(new InputStreamReader(is));..............................
